Do pesticides kill Hobo spiders?
A. – In order to kill Hobo spiders with pesticides you usually have to hit the spider directly with large doses. The problem with non discriminate spraying is that you kill the good competitor and predator spiders and insects and thus make more room for the more mobile and hardy Hobo spider. This will often lead to a worse problem with Hobo spiders as I witnessed in 1997 in my own home.
